You and Bakugou had gotten into a fight, a big one, which ended up having Iida call over Mr Aizawa. For the longest time, you and Bakugou could never get along, so instead of your normal punishment, Aizawa came up with a new one to hopefully stop this endless fighting between the two of you.

The holding hands punishment

Katsuki: "I can't believe Aizawa is making me do this.."

You both sat in two chairs, your hand in his as you're forced to sit next to each other as you hold hands.
